INGUBATOR.

Application filed November 9, 1,922. Serial No. 599,772.

To all whom t may concern:

Be it known that I, HENRY II. CHARLns, a citizen of the United States, and a resident of Manor Township, county of Lancaster, State of Pennsylvania, have invented certain new and useful Improvements in Incubators, of which the following is a specification.

This invention relates to incubators, or more particularly to drawers for incubators.

The object of this invention is to provide a drawer for incubators upon which is pivoted a square tray for carrying the eggs. It of course is desirable that the tray should lit neatly into the cabinet to provide space for carrying as many eggs as possible, and also to have means whereby the location of the eggs may be changed from time to time; therefore a further object is to provide means whereby the square tray may be conveniently turned on said pivot without unduly shaking or disturbing the eggs.

The objects of this invention will be more fully! understood freinL the following` description, taken in connection with the accompanying drawing, forming a part hereof and in which similar numerals refer to similar parts throughout the several views.

Fig. 1, is a sectional View through an incubator and shows a plan view ofthe principal elements of my invention.

Fig. 2, is a front elevation of Fig. 1, with the door 4 not shown.

Fig. 8, is a sectional view of Fig. l, somewhat reduced in size, and taken on line 3-3. The tray and drawer are shown in light broken lines when in position 'for con veniently turning the tra With reference to the drawing, 5 represents the cabinet of an incubator. 6 is a main drawer which is provided with guide strips 7. A secondary drawer 8 is adapted to iit under the strips 7 and thereby prevented from tilting when the same in drawn partially out as shown in Fig. 3.

The secondary drawer 8 is provided with guide strips 9, between which slides a strip 10. The egg tray 11 is carried by the strip 10 and is supported on the upper edge of the drawer 8 as shown at 12 when the complete apparatus is closed.

A. pivot pin 14 is fixed to the strip 10 and engages with the eye 15. The eye 15 may be formed by awasher soldered to the screen 16 which forms the bottom of the tray 11.

TNhen the incubator is in operation the eggs are placed on the screen 16 of the tra-y. After the eggs are hatched, the chicks move forward towards the light observed through the glass 17 in the door 4. They nally fall over the edge 18 of the tray into the nursery 19, formed by the drawer 8. The rear wall of the drawer 8 is made to extend above the tray 11, as shown at 24, or suiliciently high so that the chicks cannot get back of the drawer when thesame is drawn partially out of the cabinet.

Forturning the tray 11, the drawer 8, tray 11, and strip 10 are drawn to a position as shown in light broken lines, Fig. 3. When in this position the tray 11 may be conveniently turned on the pivot pin 14. The door 4 is shown in light broken lines in open position.

It is apparent that the guide strips 7 might form part of the cabinet 5 and the main' drawer 6 be eliminated without affecting that feature of my invention whereby the tray 11 may be conveniently turned on the pivot pin. However the drawer 6 is generaliy desirable when supplying my device to fit cabinets which were not originally constructed for its adaptation.

Having thus described my inventionwhat I claim and desire to secure by Letters Patent is as follows:

1`. In an incubator, the combination of a drawer, a strip carried by said drawer, guides fixed to said drawer and adapted to control lengthwise movement of said strip, a pivot pin fixed to said strip, and a square tray adapted to revolve on said pivot pin.

2. In an incubator, the combination of a cabinet, a primary drawer in said cabinet, a secondary drawer carried by said primary drawer, strips lixed to said primary drawer and adapted to prevent said secondary drawer from tilting when partially drawn, and a door adapted to close said cabinet and inclose said drawers.

3. In an egg carrying device, the com bination of a primary drawer, a secondary drawer carried by said primary drawer, strips fixed to said primary drawer and adapted to prevent said secondary drawer from tilting when partially drawn, and a rotatable tray carried by Said secondary drawer.

a cabinet having a substantially square compartment, a drawer adapted to slide in said compartment, a pivot pin carried by said 5 drawer, a squareV tray adapted to slide with said drawer in said compartment, and re- 'volve on said pivot pin7 and means adapted 'whereby said tray with said pivot pin may be moved forward relative to said drawer l0 and thereby permit Said tray to be rotated on said pivot pin. 5. In an incuba tor the combination with a cabinet, a drawer in said cabinet, a pivot pin oarrled by said drawer, a trayi supported by the side walls of said drawer and adapt- 15 Y ed to revolve on said pivot pin, means adapted whereby said tray with said pivot pin may be moved forward relative to said drawer, and a rear wall section forming part of said drawerand extending to the 20 top of said tray.

In testimony whereof I affix my signature,

HENRY H. CHARLES.
